:The improvement consists of providing a ,valve seat that cari be easily replaced, that "is 10 easily accessible for the purpose of inspecting` and cleaning, admits of an unobstructed ilow4 of the liquid, and of a new 4and improved rnotion for closing the valve..

My invention is illustrated in the'accompanying drawing, of which Figure 1 is a planviemFig. 2 is a vertical sectional elevationand Fig. 3 a; vertical sec? tional-elevation o fa modified form of Vthe lvalve..

I willexplainthe. workings and arrange; ment of my invention by means of Fig. 3, be.- ing the most easily understood.

-A is the valve bodywith athreaded portionto he secured to a eask or, gas, pipe, and is therefore, stationary. y

Bis that part'of the valve'haying theout-l letI opening, which is shown as threaded to receivea coupling or anyother pipe coI-1nec tion. B is connected toA by-a hinge (I and, 30 by la latch 1),.vvhihy is hinged at E, and Works over 'a curved back boss F.l To insure a 'tight fit of vthe part B against A, a ringshaped gasket is interposed between said two parts, and the latch D is so arranged that ciently to insure vagainst anyv lirpid passing'v through between parts Aand My improved valve,` however, is soarranged that gasket H also serves as a seat for the 40 valve, piston, which may be seen from Fig. 3,

where H is apiston that is actuated by means of a hand wheel I and forced 'against the gaslSet'G.

In my valve I prefer to use a gasket of elas- '45 tic material, such as rubber; it may however.,- consist of other elastic material. I have madef'provisions to yprevent overcompresby two connecting which hinges on e part B. These e 'gasket G, 'pin upon the nut Nwould be fWasher between the-body, part and-the cas-. -85

-sion of the rubber letting vthel piston'H come to a stopagainst an annular metal -projection K, when the gasket is compressed to about 'of its original thickness.' I have vfound vthat rubber compressed to not more than this thickness will not lose its elasticity v so easily as when compressed to less than .of

its original thickness.`

InxFigs.' 1' and 2 is shown a.'quick motion foropening andfclosing the an le valveof my improved construction'. ig.A 2) is a rod attached toA piston H. It has .a threaded part M, on which is screwed a nut N: Nut N is drilled and pinO, inserted in the bore, connectsthe valve stemi Lto lever P, forming a v'link connection Withpin O. Lever P .has a second pin Q parallel topi'n O and connected ieces R'to a thirdpinS,

hinges -form 'a toggle ver", whose workings; are easily' understood Without'urther" descri tion.4 In ord'e'r to regulatethe for'pe wit which the iston Hfshould seat against i can beunscrewefh where- 'screwed up or down the piston -rod L', half- .a turn at the time.

The piston rod Ii'isslotte'd at its'upper end and allows for the adjusting movement of pin O. '.What I claim asm yinyentonand desire to secure by Letters atent is In a valve, the combination-'oa bodylpartcontaining the seat, a casing hinged't'othe body part substantially in the planeof the seat and containing a yalve,.a'gasket serving as avalve seat and sunultaneously as a ing, and .means for forcing -and'flocl'ring. the valve upon its seat.'
